All I'm saying is that their "findings"; what little we know about them, seem odd. I'd love to see the actual results of their marketing research. From what I remember of the parts they did reveal, there wasn't much in the way of market research that would lead to any conclusion whatsoever about "fragmenting the consumer base." They were more concerned about player habits in general -- how often folks played, how many people played, which games they played, D&D's market share relative to its competitors, etc.
I doubt that WotC would release the
details of the research that would show it. However, the basic trend would likely be easy enough to find if the right data was available.
Fudging a time frame here (because I don't have a timeline for D&D settings available):
Forgotten Realms becomes D&D's best selling product over Greyhawk giving them 3 settings ("Mystara", Forgotten Realms, Greyhawk).
Dark Sun is released, sales of Forgotten Realms goes down.
Al-Qadim is released, sales of Dark Sun and Forgotten Realms goes down.
Birthright is released, sales of other settings go down.
Planescape is released, sales of other settings go down.
New emphasis is placed on Greyhawk, sales of other settings go down.
Now, certainly there will be variations. Planescape's growth would likely hurt some settings more than others. Still, the evidence would likely be there.
